To @Z whom t may concern.:

Be it known that we, JOHN S. SANGER, residing at Orange, and RODERICK M.SANGER, residing at East Orange, Essex county, New Jersey, citizens ofthe United States, have invented certain new and useful Improvements inApparatus for Applying Tooth-Powder, fully described and represented -inthe following specification and the aecompanyin g drawings, forming apart of the same.

The object of this invention is to furnish a convenient means ofpreserving the tooth powder, and applying it to the brush; and it mayalso alford a means of sustaining the brush when not in use. Y

The invention consists primarily of a back piece adapted to hang upon awall, a tooth powder receptacle projected from the front side of suchback piece with an outlet above the bottom of the receptacle, a movablescreen for discharging the powder, and a tray projected from the backpiece below the outlet and held removably thereon.

The invention will be understood by reference to the annexed drawings,in which- Figure 1 is a front elevation of the entire apparatus. Fig. 2is a partial sectional view of the same on line 2, 2, in Fig. 1. Fig. 3is a plan in section on line 3, 3, in Fig. 1, showing an alternativeconstruction for the screen. Fig. e is an edge view of the screen shownin Fig. 3. Fig. 5 is a side elevation of the apparatus with toothbrushes supported in the clips and upon the guide, the handles of thebrushes being broken. Fig. 6 is a vertical section of the lower part ofthe apparatuson line 6, 6, in Fig. 3.

A is the back piece which is formed of a sheet met-al plate with beadedborder and hollow back. The border is drawn with diagonal lines torepresent an imitation of a cable pattern. The back piece carries upon.its front side the sheet metal receptacle B which may be attached to theback piece by lugs b (shown in Figs. 2 and 6) extended through openingsin the back piece and clinched behind the saine. The receptacle has acover Gwhich is jointed to the back piece byhinge g and pin g locatedwithin the hollow back. The cover is tted tightly to a flange B upon thetop of the receptacle. The outlet E in the bottom of the receptacle isformed with upturned flanges e, as shown in Fig. 6, which support adischarge platef havinga discharge opening f A screen h or h is fittedmovably upon the plate above such opening to prevent the discharge ofthe powder until desired, and such screen may be formed with holes e',as shown in Fig. 2, the opening f", as shown in Fig. 3. The screen h ispivoted at one end, and has a handie j projected through the side of thereceptacle at the opposite end, to vibrate it thereby; as the toothpowder packs in such manner that it falls through the holes t' only whenthe screen is in motion.

Where a perforated screen is merely vibrated over the opening in thedischarge plate, the opening may be made as large as the outlet atwhichthe brush is applied; but where the screen is withdrawn from theopening, as in Fig. 3, the opening is made quite narrow, as shown at h',to restrict the discharge in the desired degree.

The screen h is tted between ribs f2 upon the platef, as shown in Fig.6, and is formed upon its upper side at the inner end with several pinskadapted to loosen the powder when the screen is slid endwise, as shownin Fig. 3, thus loosening the powder temporarily and securing asufficient discharge of the powder through the opening ff.

Theback piece A is formed, below the receptacle, with a loop Z which ispressed forward from the metal of the holder, and the tray O is shownwith a foot m bent downwardly to it within such loop, thus securing thetray detachably upon the holder below the outlet E. Y

The holder is provided near one end of the outlet E with clips forming aguide o to hold the tooth brush handle p, as shown in Figs. 1 and 5, soas to support the bristles of the brush beneath the outlet E.

The anges e which support the discharge plate f a little distance abovethe bottom of the receptacle, are preferably converged inward, as shownin Figs. 2 and 6, and the chamber or passage between the discharge plateand the outlet is thus expanded outwardly.

or be arranged to uncoverl IOO The outlet is made a little smaller thanthe usual area of the bristles upon the tooth brush, to wholly preventthe bristles from crowding into the chamber or passage.

The elevation of the discharge plate above the bottom of the receptaclenot only forms a closed chamber for the diffusion of the powder betweenthe discharge plate and the iiange, but it thus prevents the bristles ofthe brush from coming in contact with the plate. l

As it is common to wet the brush before applying the powder, the waterupon the brush if allowed to touch the discharge plate, would cause thepowder to stick in the discharge opening and thus render the apparatusinoperative. The construction therefore provides effectively for holdingthe wet bristles aty a suitable distance below the discharge plate,while it prevents the loss of powder which would result if it were notconfined in a closed chamber.

A sufficient supply of powder can be discharged through an opening muchsmaller than the surface of the bristles, and the flaring form of theoutlet produced by the inwardly converging flanges e thus permits thescattering or diffusion of the powder over the bristles as it isdischarged through the openingf by the movement of the screen. Suchscattering being Ieffected in a diffusion chamber, the loss or waste ofpowder is almost wholly prevented.

Any surplus powder is caught by the tray O, and as the tray is helddetachably by thev foot m, it may be kreadily removed from the holder tothrow out the powder or restore it to the receptacle.

Spring clips D are shown projected at one side of the receptacle toengage the neck of the tooth brush handle, and thus support the toothbrush when not in use. The whole device furnishes a convenient means ofstoring and applying the powder and of sustaining the tooth brush inreadiness for use.

To close the outlet tightly, so as to prevent the leakage of powder intransporting the receptacle, we provide a swinging gate n of formsimilar to the ,screen h, pivoting the same to the bottom of thereceptacle at one end of the outlet, and fixing a catch n tothereceptacle and to the opposite end of the outlet, to press the gateclosely against the outlet. The gate is shown open in Fig. l, and,yclosed in Fig. 6, to prevent the discharge of the powder. The gate isshown as a thin flat plate, and the catch isforined as a sloping lugadapted to crowd the gate upward against its seat upon the receptacle,when4 the4 edge' of the gate is forced beneath the lug. The

gate thus affords a cheap and effective means of closing the outlettightly.

From the above description it will be seen that the diffusion chamber isa very important feature of an apparatusfor applying powder economicallyto a moistened tooth brush. To form such chamber in asuitable manner,the outlet should correspond to the shape of the tooth brush and be madea little smaller than the area of the bristles, to prevent theiradmission to the chamber. In such construction, the movable screen formsin reality the top of the didusion chamber, as it affords," when not inuse, a partition between such chamber and the powder in the receptacleabove.

Having thus set forth the nature of the invention, what is claimedherein is l. As a new article of manufacture, the sheet `metal backpiece A provided upon one side with the receptacle B having the outletin the bottom with movable screen, and the back piece having the loop Zbelow such outlet, and the trayC adapted to projectv from the backpiece, and provided with the foot m bent downwardly and fitted removablywithin Lthe loop, asand for the purpose set forth.

2. As a new yarticle of manufacture, the

back piece A provided upon one side with the receptacle B having theoutlet in the bottom with movable screen, and the tray C projected fromthe back piece and attached removably to the same below the outlet, and

the spring clips o projected from the baclr piece below the outletandarranged to support the tooth brush against the outlet when applyingthe powder, substantially as kset forth.

3. As a new article of manufacture, the tooth powder receptacle B havingin the bottom the outlet E corresponding in shape to' the outline of thetooth brush bristles, and provided with a diffusion chamber above suchoutlet, a discharge plate having a discharge opening and fixed at thetop of the diffusion chamber, with a screen fitted movably to the plate,the whole arranged and operated to provide, with the brush applied tothe outlet, a closed space between the screen and brush, within whichthe powder is scattered upon its discharge from the receptacle,substantially as herein set forth.

4. As a new article of manufacture, the tooth powder receptacle B havingin the bottom the outlet E corresponding in shape to the outline lof thetooth brush bristles, and provided with a diffusion chamber above suchoutlet, a discharge plate xedat the top of the diffusion chamber andprovided with a slot, as f, the screen h fitted to move longitudinallyover the slot upon the upper side of the discharge plate'and extendedoutward through the wall of the receptacle, and the pin lo projectedfrom the upper side of the screen h over the slot to loosen the powder,substantially as .herein set forth.
